Description

Technical Field

[0001] This invention relates to the field of glass printing and processing, and in particular to a glass edge printing production line. Background Technology

[0002] Glass edge printing is a special printing process that prints images and text on the edges of glass products. It is commonly used on various glass sheets, glass containers, and other glass products to enhance their decorative and personalized appeal.

[0003] Traditional printing equipment positions the glass in the center of the printing area, while edge printing is positioned separately on one side of the printing area. Traditional printing requires manual operation, and inexperienced workers need to spend a lot of time on plate matching, resulting in decreased production efficiency. Moreover, it is difficult to guarantee that the printing accuracy is particularly precise, especially for some large glass products where only one edge is printed. Manual printing tests are required, and prolonged contact with ink also poses certain hazards to workers. Therefore, improvements are needed. Summary of the Invention

[0004] The main objective of this invention is to provide a glass edge printing production line that can effectively solve the technical problems raised in the background art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A glass edge printing production line includes a frame. A lifting and conveying mechanism and a screen frame mechanism are mounted on the top of the frame. The lifting and conveying mechanism includes a lifting cylinder and four drive shafts. Both ends of the four drive shafts are movably mounted inside the frame via bearing seats. A connecting rod is movably connected between each drive shaft. Guide shafts are movably mounted on both ends of each drive shaft. A common transmission wheel frame is mounted on the top of the guide shafts outside the four drive shafts. The screen frame mechanism includes two first slide rails. A rodless cylinder is installed inside each of the two first slide rails. A lifting assembly is installed at the bottom of each of the two first slide rails. A connecting member is installed on the top of the first slide rails. A clamping assembly is installed on the top of the connecting member. A screen frame is installed between the two clamping assemblies. The bottom of the first slide rails is mounted on the top of the frame via a lower fixing frame. Several screen clamping cylinders are installed on the top of the clamping assembly. Bracket clamping cylinders are installed at both ends of the clamping assembly.

[0007] As a further embodiment of the present invention, the angle between the position where the connecting rod and the drive shaft are connected and the position where the bottom end of the guide shaft and the drive shaft are connected is 90°, and the connecting rod, the guide shaft and the drive shaft are all movably connected.

[0008] As a further embodiment of the present invention, the two clamping components are symmetrically installed, and the mesh frame is slidably positioned on top of the first slide rail.

[0009] As a further embodiment of the present invention, a printing mechanism is installed on the top of the frame body. The printing mechanism includes several air-blowing and air-suction screens. Several sets of air-blowing and air-suction screens are distributed and installed in the frame body. Long-side positioning modules are installed on both sides of the air-blowing and air-suction screens. Straight-line modules are installed at both ends of the bottom of the air-blowing and air-suction screens. A second slide rail is installed at the bottom of the straight-line module. Several positioning points are installed on the top of the straight-line module. Air-blowing and air-suction interfaces are opened at the top and bottom of the air-blowing and air-suction screens. A double-stroke cylinder is installed in each of the two long-side positioning modules. A fine-tuning handle is installed on the outside of the double-stroke cylinder.

[0010] As a further embodiment of the present invention, a plurality of the blowing and suction mesh plates are arranged in a matrix, and the straight module is used for short side positioning and adjustment.

[0011] As a further embodiment of the present invention, the linear module is slidably arranged via a second slide rail, and the air blowing and suction mesh plate and the mesh frame are synchronously raised and lowered.

[0012] As a further embodiment of the present invention, an air suction mechanism is installed at the bottom of the air blowing and suction mesh plate. The air suction mechanism includes two directional valves, a turbine air pump, an air blowing and suction seat, and a lifting printing frame. An air inlet is opened at the top of the directional valve, and an air outlet is opened on both sides of the directional valve. A silencer is installed on the outside of one of the air outlets, and the other air outlet is connected to the air blowing and suction seat. A valve plate is installed inside the directional valve.

[0013] As a further embodiment of the present invention, the lifting printing frame is installed on the top of the frame and above the air blowing and suction screen, and the bottom of the lifting printing frame is equipped with an ink return knife and a printing knife.

[0014] As a further embodiment of the present invention, the air inlet of the steering valve is connected to the turbine air pump via an air pipe, and the air outlet of the steering valve is connected to the blow-suction air seat via an air pipe.

[0015] As a further aspect of the present invention, the top of the air-blowing and air-suction seat is provided with a plurality of air-blowing and air-suction grooves, each air-blowing and air-suction groove being connected to the air-blowing and air-suction interface of each air-blowing and air-suction mesh plate.

[0016] As a further embodiment of the present invention, a valve body cylinder is installed on the outside of the steering valve, and the valve plate inside the steering valve is driven to rotate by the valve body cylinder.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] By setting up a lifting and transmission mechanism and a screen frame mechanism, the guide shaft drives the transmission wheel frame to lift and lower, which facilitates lifting and conveying during printing. After the glass printing is completed, it can be transferred to the next equipment. The screen frame can be pulled out by sliding, which facilitates the replacement and cleaning of the blowing and suction screen.

[0019] By setting up a printing mechanism, the short side positioning module and the long side positioning module at both ends position the glass to the positioning points on both sides. With the lowering of the frame, it is ensured that the glass does not shift during printing. The side positioning can be adjusted by the fine-tuning handle, which facilitates the initial positioning and printing adjustment, ensures no deviation after printing, and greatly improves the printing effect.

[0020] By setting up an air intake mechanism, the valve plate inside the steering valve rotates to alternately open and close the muffler and the air outlet, realizing air intake and air blowing. This allows the glass to be positioned and fixed by adsorption, further preventing displacement during printing. The air blowing mode prevents the glass from creating a vacuum after air intake, which could easily cause damage when the conveyor wheel is raised for transport, thus facilitating the operation of workers.

[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0037] like Figures 1-14As shown, a glass edge printing production line includes a frame 1. A lifting and conveying mechanism 2 and a screen frame mechanism 3 are mounted on the top of the frame 1. The lifting and conveying mechanism 2 includes a lifting cylinder 6 and four drive shafts 7. Both ends of the four drive shafts 7 are movably mounted inside the frame 1 via bearing seats. A connecting rod 8 is movably connected between each drive shaft 7. Guide shafts 9 are movably mounted on both ends of the exterior of each drive shaft 7. The top of the guide shafts 9 on the exterior of the four drive shafts 7 is equipped with the same transmission wheel frame 10. The screen frame mechanism 3 includes two first sliding... The first slide rail 11 is equipped with rodless cylinders 12. The bottom of the first slide rail 11 is equipped with lifting components 13. The top of the first slide rail 11 is equipped with connectors 14. The top of the connectors 14 is equipped with clamping components 15. A mesh frame 16 is installed between the two clamping components 15. The bottom of the first slide rail 11 is installed on the top of the frame 1 through a lower fixing frame 17. Several mesh plate clamping cylinders 18 are installed on the top of the clamping components 15. Both ends of the clamping components 15 are equipped with bracket clamping cylinders 19.

[0038] In this embodiment, the angle between the position where the connecting rod 8 and the drive shaft 7 are connected and the position where the bottom end of the guide shaft 9 and the drive shaft 7 are connected is 90°, and the connecting rod 8, the guide shaft 9 and the drive shaft 7 are all movably connected.

[0039] By extending and retracting the telescopic rod in the lifting cylinder 6, the corresponding drive shaft 7 is driven to rotate. Through the connection of the connecting rod 8, the other drive shafts 7 are driven to rotate, causing the corresponding guide shaft 9 to rise and fall along the lifting track, thereby realizing the lifting and lowering of the transmission wheel frame 10.

[0040] In this embodiment, the two clamping components 15 are symmetrically installed, and the wire frame 16 is slidably positioned on top of the first slide rail 11.

[0041] The pull-out wire mesh frame 16 is connected to the lower fixed frame 17 via a slider in the first slide rail 11. The slider is moved by the rodless cylinder 12, so that the wire mesh frame 16 can be easily pulled out on the first slide rail 11.

[0042] In this embodiment, a printing mechanism 4 is installed on the top of the frame 16. The printing mechanism 4 includes several air blowing and suction screens 20. Several sets of air blowing and suction screens 20 are distributed and installed in the frame 16. Long side positioning modules 21 are installed on both sides of the air blowing and suction screens 20. Straight modules 24 are installed at both ends of the bottom of the air blowing and suction screens 20. A second slide rail 26 is installed at the bottom of the straight module 24. Several positioning points 23 are installed on the top of the straight module 24. Air blowing and suction interfaces 25 are opened at the top and bottom of the air blowing and suction screens 20. Double-stroke cylinders 28 are installed in both long side positioning modules 21. Fine adjustment handles 22 are installed on the outside of the double-stroke cylinders 28.

[0043] The transfer wheel frame 10 transports the glass to the printing setting area. The glass is positioned at the side positioning point 23 by the straight modules 24 at both ends and the long side positioning modules 21 on both sides. The fine-tuning handle 22 facilitates fine-tuning of the side positioning.

[0044] In this embodiment, several air blowing and suction screens 20 are arranged in a matrix, and the straight module 24 is used for short side positioning adjustment. By adjusting the movement of the straight module 24 and the positioning point 23, the glass is positioned on the short side to ensure no deviation after printing.

[0045] In this embodiment, the linear module 24 is slidably arranged via the second slide rail 26, and the air blowing and suction screen 20 and the screen frame 16 move up and down synchronously. The air blowing and suction screen 20 moves up and down with the screen frame 16, and the air blowing and suction screen 20 on the printing table draws air to ensure that the glass sheet does not shift during printing.

[0046] In this embodiment, a suction mechanism 5 is installed at the bottom of the air blowing and suction mesh plate 20. The suction mechanism 5 includes two diverting valves 30, a turbine air pump 31, a air blowing and suction seat 32, and a lifting printing frame 38. An air inlet 34 is opened at the top of the diverting valve 30, and an air outlet 35 is opened on both sides of the diverting valve 30. A silencer 36 is installed on the outside of one of the air outlets 35, and the other air outlet 35 is connected to the air blowing and suction seat 32. A valve plate 37 is installed inside the diverting valve 30. The air blowing and suction seat 32 is connected to the air blowing and suction interface 25 of the air blowing and suction mesh plate 20 through an air pipe to realize air blowing and suction.

[0047] In this embodiment, the lifting printing frame 38 is installed on the top of the frame 1 and above the blow-suction screen 20. The bottom of the lifting printing frame 38 is equipped with an ink return blade 39 and a printing blade 40. The lifting printing frame 38 causes the printing blade 40 to descend and move from back to front for printing. The printing is completed by the printing blade 40 rising.

[0048] In this embodiment, the air inlet 34 of the steering valve 30 is connected to the turbine air pump 31 through an air pipe, and the air outlet 35 of the steering valve 30 is connected to the blow-in / suck-out air seat 32 through an air pipe. The steering valve 30 is used to switch the alternating opening and closing of the two air outlets 35 to perform blow-in / suck-out operation.

[0049] In this embodiment, the top of the air blowing and suction seat 32 is provided with a plurality of air blowing and suction grooves 33. Each air blowing and suction groove 33 is connected to the air blowing and suction interface 25 of each air blowing and suction mesh plate 20. After the glass is positioned, the air blowing and suction mesh plate 20 descends and adsorbs the glass onto the workbench through the suction state to prevent the printed glass from shifting.

[0050] In this embodiment, a valve body cylinder is installed on the outside of the steering valve 30. The valve plate 37 inside the steering valve 30 is driven to rotate by the valve body cylinder. The valve plate 37 is rotated by the valve body cylinder to realize the blowing and sucking state of the steering valve 30.

[0051] It should be noted that this invention is a glass edge printing production line. In use, the bottom of the pull-out frame 16 is connected to the lower fixed frame 17 via a slider on the first slide rail 11. The lower fixed frame 17 connects and fixes the slider on the rodless cylinder 12 to the pull-out frame 16 via a connector 14. When the slider of the rodless cylinder 12 moves, it easily pulls the pull-out frame 16 out along the first slide rail 11. The pull-out frame 16 is then ready to place the blow-and-suction screen plate 20. The distance between the clamping components 15 of the blow-and-suction screen plates 20 on both sides is adjusted, and the pull-out frame 16 is pushed back into place. After the blow-and-suction screen plate 20 is in place, the screen plate clamping cylinder 18 on the clamping component 15 presses the blow-and-suction screen plate 20 tightly, and the bracket clamping cylinder 19... Locking ensures the air blowing / suction mesh plate 20 is fixed in position. During transmission, the lifting cylinder 6, through the retraction of the cylinder rod, drives the drive shaft 7 to rotate, and through the connecting rod 8, drives the other drive shafts 7 to rotate synchronously, causing the guide shaft 9 to rise along the track path. Conversely, when the cylinder rod extends, the guide shaft 9 lowers. The extension and retraction of the lifting cylinder 6 drives the guide shaft 9 to rise and fall. The guide shaft 9 is fixed to the transmission wheel frame 10 with fasteners, thereby realizing the raising and lowering of the transmission wheel frame 10. When transferring glass, the transmission wheel frame 10 rises to transfer the glass to the printing area. When printing, the transmission wheel frame 10 descends. After printing is completed, the transmission wheel frame 10 rises to transfer the printed glass to the next device. During printing positioning, the transmission wheel frame 10 transfers the glass... The glass is sent to the printing setting area, and is positioned to the side positioning point 23 by the short side positioning modules at both ends and the long side positioning modules 21 on both sides. The frame 16 descends, and the air-blowing and suction screen 20 draws air to ensure that the glass does not shift during printing. If there is a deviation between the printed pattern on the air-blowing and suction screen 20 and the glass printing position during the initial positioning, or if the positioned glass is slightly loose, it can be finely adjusted by the side fine-tuning handle 22 to ensure that there is no deviation after printing. After the glass is positioned, the air-blowing and suction screen 20 descends and needs to be adsorbed on the worktable before printing. During adsorption, the turbine air pump 31 works, the valve body cylinder of the first steering valve 30 does not move, and the valve plate 37 inside the steering valve 30 is in the closed silencer 36 exhaust state. At this time, the turbine air pump 31 connects with the air-blowing and suction screen 20 through the air pipe. The air intake and exhaust port 25 in the air intake screen 20 is connected. The valve body cylinder of the second diverting valve 30 is pushed out, which switches the valve plate 37 in the diverting valve 30 to connect with the silencer 36. The airflow is discharged from the air outlet 35 in the silencer 36, realizing the air intake state. After the glass printing is completed, it is conveyed from the workbench to the next equipment that needs to be blown. To prevent the vacuum generated after the glass is blown, it is easy to be damaged when the conveyor wheel frame 10 is lifted for conveying. The valve body cylinder of the first diverting valve 30 is activated to put the valve plate 37 in the state of opening the silencer 36 to draw in air. The valve body cylinder of the second diverting valve 30 is retracted, which switches the valve plate 37 of the diverting valve 30 to the opposite direction, so that the airflow is blown out from the air intake and exhaust port 25 on the table of the air intake and exhaust screen 20, realizing the air blowing state.During printing, the lifting print stand 38 lowers the printing blade 40 and moves it from back to front to begin printing. The printing blade 40 and the blow-suction screen 20 rise. After printing, the return ink blade 39 lowers and returns ink from front to back. After ink return is complete, the transfer roller frame 10 rises for transport.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
